I sat in his class for a day and dropped it. It was so boring. He refered to elements as "things."

Not a good teacher. He can't finish a thought and if he does it makes no sense. He seems inconvenienced by questions from students. Also, if you don't get the review sheet answers you will not do well on the tests. Avoid at all costs

he knows something, as he managed to achieve a PhD but he sure can't impart any of that knowledge to anyone. he's present for the first half hour of lab every lab, but then is missing for the next three hours. incredibly unhelpful and he stinks of something unidentifiable (something fermented?)

Nonsense teacher I ever had.

horrible teacher.. doesn't help u out.. and always talks about aliens being "out there".. needs to get a life..u feel bad for the guy..had him over the summer.. don't take him if u can help it.

GET OUT NOW!!!he is the reason i will not be in the FBI any longer bc i switched majors bc he turned me off of chemistry! i dropped his course b4 my GPA dropped first! if u stay ur favorite words will be "uh and umm" and you will def. catch up on ur sleep!im sure he was a good teacher at one point but needs to retire now...not up with the times...

Barth is a troll. I had to drop the class because he was impossible. His reviews do not reflect the content of the test. He is the King of the Babble-ons. He goes off on tangents that have no significance to the material. I got help from a tutor and dropped out with a C. The tutor was responsibe for the 76% I knew in chem. Dr. Barth was of no use.

he made me want to kill myself...but i settled for switching majors and then switching schools! he rambles about elements being things and about coffee and that horrible soup that he eats. single worst teacher ever. avoid taking him at all costs.

counted over 200 "uhhh" or "ummm"s in less than a half hour. just cant pay attention...I will give him some credit he does have ok tests because of bringing a index card but you better read the book

The worst professor at the Unversity. He is very unclear and is all over the place. Do yourselves a favor and take Townsend. Barth's exams, however, are very basic/easy if you do understand the material.

worst teacher ever. he wasn't clear in class at all and i guarantee i would have failed that class if i hadn't had all the concepts in AP chem in hs. unless you had AP chem in hs and feel confident in what you know from that, DON'T take barth

Basically if I had not taken Honors Chemistry II the year before I would probably not be doing well at all. If you like listening to ummm well ahh you see its like..... ummm, then this is the class for you. Townsend came in for one class and it was totally different and easier to understand.

WORST TEACHER EVER! Don't take his class unless you can teach yourself! His lectures are worthless!!!!!!!

Dumbest smart guy in the whole faculty. Easy tests amusing but HORRENDOUS teacher. He cant explain anything for his life and will get his own example problems wrong on the board. He is most likely senile and you will see him randomly walking around dragging his feet like an idiot. DO NOT TAKE HIM IF YOU WANT TO UNDERSTAND CHEM.

Barth is really a horrible teacher. He does not know how to teach. Going to class is pointless, I haven't learned anything from him; tutoring is a must! He rambles on about random, irrelevant information and don't bother asking questions or going to office hours, he doesn't answer your question and again will ramble on about pointless information.

You have to do the majority of your work and learning outside of the classroom; Barth does not know how to teach. He draws weird pictures on the board and is very unorganized in his work. He stutters way to much and messes up a lot. I would not recommend him to anyone. His tests may be easier than other professor's, but only if you teach yourself.

i would have to say he is one of the most unclear teachers that i have ever had. when he cant explain something he uses the word stuff and his lectures go in circles at best. were about 2/3 of the way through the semester now and have lost well over half of the class. save your GPA save yourself and get the hell out of his class if you can!

Dr. Barth is a really smart man but he cannot teach AT ALL. He knows everything when it comes to the subject matter but he stutters a lot and goes on tangents during his lectures. Although I haven't learned much in his class, his labs are written out in detail so all you have to do is follow directions and show up and you'll get an A for that lab!

This guy can not teach. 20 minutes of youtube do a better job than 2 hours listening to Barth.

Seems very easy at first then he gets completely confusing and jumps from topic to topic. He stutters a lot while screaming during lecture so it makes it more confusing. Drops 5 lowest quiz scores, final is optional. Midterm is so hard I got a 38%. I wouldn't recommend this class, take geology or physics because I've heard way better things.

I respect how knowledgable he is on the subject. However, he really is not a good professor. Disorganized in his lectures, can never understand what we're really talking about, especially during his tangents. Nice guy, but needs to learn how to effectively teach. NOT AN EASY A. It's very hard and the tests are not easy like he claims them to be.

He knows what he's talking about and he's excited about the topic. However, he's just not a good professor. His excitement doesn't rub off on you and he jumps around in lectures. He uses only powerpoints that you don't have access to and goes too fast. He cares but he's not good at explaining anything and you will feel lost in this class.

Dr. Barth is a very nice man, however his teaching skills are not good. You have quizzes on every chapter, he says they're like the homework, but they're not. He gives you homework-never gets graded. He gives few tests but they're very hard, my class had over half of the class receive grades BELOW 50 on the first exam. Avoid if you can.

If you are a chemistry major, you will have to take seminar with Dr. Barth. This s an absolutely brutal class, not because it's hard but because of the way he "teaches". His lectures are rambles that are littered with ums and uhs. His grading of powerpoint/ poster is based soley on his personal preference. I just wish a different professor taught.

I took this class bc I suck at science & i thought it'd be easy. I was wrong. There was a quiz every single class. If you don't know basic chem, do not take this class. He does not help you learn chem & just assumes you know it. He knows what hes talking about, but he's just not a good professor. It's so easy to get lost. Don't do this to yourself

Dr. Barth is not a good lecturer at all. It can be extremely hard to read what he puts on the board at times and he barely ever uses power points in class. His tests are fairly easy, though, and he dedicates an entire class to reviewing the chapters that are on it. He also gives his students access to his lecture notes and they're really helpful.

I recommend not even going to his lectures. His class is very hard to follow because he tells you a bunch of random information in no particular order and you cannot read his handwriting. There is alot of homework but it is fairly easy to get a good grade on it. Tests are not too hard, but are worded vaguely and have some curveball questions.

This class makes me cry. I am struggling so much. He is such a bad professor. He can't teach anything. I find it very difficult to follow him. It's so easy to get lost. There is really no point of going to his lectures. All my advice for future students is 1) don't procrastinate, DO NOT 2)Read the Textbook, take notes 3) Watch YT Vids

Dr. Barth is completely disorganized and unprepared for his lectures. He does not provide any notes to the class and/or assist in teaching. He is unable to answer questions and unfamiliar with the homework assignments. He gets flustered when asked questions and does not prepare the class for lecture, just starts with no into of topic. HORRIBLE

Dr. Barth's lectures are all over the place, he doesn't take the time to prepare for the class and goes on rants about random topics. He assumes everyone knows the information and in turn doesn't teach it. His homework is very intense and long, do NOT delay on starting it and utilize the tutor available, it'll help. You pretty much teach yourself.

He is probably the most unorganized professor I've ever had. Online classes are the biggest challenge when you have an unorganized professor so he's making this semester dreadful. Doesn't like answering questions and can get snarky as if you should know things already. There's no intro to any of his lectures, he just starts writing on the board.

Single worst professor I have ever had. He did not care whether information was conveyed or not. Poor job presenting material. Method of tests was unorthodox and poor. Graded test like an Olympic Judge (1-10 for a given question) with no rationale. Completely goofy, unprofessional, and presenting minimal value for the course. Awful.
